To all whom #may conocia." t L- Be 'it known that LALBERT H. EHRLICH, a

citizen ofy the United Statesfresiding at St.v

Joseph, in the county-of Buchanan and State" of ,Missour'n have-f invented certain new and i' useful lImprovements iny Refrigerators or Cold-Storage Room s,jof which'the following Thisinvention relates, toy a Aretrigerator or 10 cold` storage Vroom Vand has for its objett L Vto 'provide means for insuring ayrapidl and continuous circulation of air Vfrom the upper cooling: compartment to the"lowerf"cooled i shield QOVtoiproperly protect Vthefopening compartment. A j 1 Figure 1 isa perspective view broken away "to clearly illustrate the invention.

' Fig. 2 is a transverse'section through the Aupper part of the refrigerator. Y,

Fig. 3 is -a modified view showing a shield y over the central opening when itis desirable tov use ice as a cooling mediumf..l

The numerals 1 and 2 indicate the frontl Vand side walls respectively, the front wall being providedwith a setof doors 3 for access'to the lower'provisioncompartment, the

side walls beingprovided with windows 1.-- The bottom andiroof'or top wall v6 aswell as the walls 1-and2 being suit-ably insulated as illustrated.

porting'joists 7 adapted'to supporta cold storage'pan arranged inthe upper cooling 4o walls ofthe refrigerator formingan air duct 1 therebetween, suitably spaced braces llfll' being arranged between the outer walls and the balie` boards'. As/disclosed in Fig.v 2

oists 8 slant downwardly toward the center on their'lower edges'as at` 12 being provided centrally thereof on the lower side with .a

recess 13. The numeral 14' indicates 'pans secured to the edges of'joists 8 said pans being properly insulated to avoid condensa` 5o tion. These pans are preferably spaced to,

form a central opening 15 which servesas a cold air duct to permit the cooled air to pass dowiiwardy into the lowerprovision conipartment and upwardly through the spaces 1 between the outer' walls andthe baffle boards as indicated in Fig. 1V by arrow. fGutters .The wall portions have secured thereto .on the side directly above the doorssupf arearranged alongitlieinner edgeofthe "l collected-uponitliepans;y y ilrrran'ged within the chamber `formed by ns tovca'rr'y oilienyflig'uid thatmaybe the. batiie'boards areQaplura-lity)of brine tanksy `1"? being vprovided with'suitable `cool' Joistsi "serve 'to -in'siire proper spacing of' the 'tanks'to' forman' openingA which reg- KVisters wlithjthe' opening 15 whereby; ythe cooled .air :may pass vdownwardly there'f openingfl""mayv be'. bridged vover with"a' .ing coils 18.

preferably constructed in such a manner that the compartment may bey shipped in a knoclc. down form thereafter being put together or assembled in the refrigerator, it being understood-that this form of cooling storage pan is made independentlyof any. particularY form of refrigerator `andis adapted to be applied even to one. in use.;

It will thus beseen that I `have, constructed va cooling pan in such almanner'that a circulation is maintained in the refrigerator.
